QKI-SPS100 (SPI STEPPER)
*** WARNING ***
You must power the rails that have this Kard installed with +24V before applying USB power, if you apply USB and +24V at the same time or USB power first you risk blowing this Kard. This is due to SPI of the L6472 not working properly without high voltage applied to the chip.
*** WARNING ***
